nodejs - http.createServer seems to call twice

Generally, favicon.ico is fetched by the browsers. So, the two calls.

Solution to this issue can be checking for request URL if it's fetching favicon.ico or not.

http.createServer(function (req, res) {
    if (req.url != '/favicon.ico') {
        // do your stuffs
    }
}).listen(3500);

That is normal - your browser makes more than one call.

Most browsers make a call to grab /favicon.ico for example.

Try to log the url:

console.log(req.url);

and you'll see what's being called.
